<p>*** WARNING: AS DRAFTED, CANNOT use within nontrivial scripts or functions
because the <code>stopApp()</code> seems to interrupt other processes and cause problems -
and seems related to a quirk seen if a script or function calls radiobox() twice -
it will work the first time but show a blank popup window the 2d time...
e.g., if you  try to do this:
radius1 &lt;- radiobox()
radius2 &lt;- radiobox()
May all be related to this issue: https://github.com/rstudio/rstudio/issues/13394</p>
<p>Note this function could be defined as an RStudio addin and assigned a keyboard shortcut, if that is useful.</p>
